程式例

#include <alloc.h>屑凝妹汽
#include <阿棗潤檔string.h>蒸臭汗
#include <dos.h>
int main(void)
{
char far *fptr;

/* copy "Hello" into allocated memory */
/*
Note: movedata is used because we might
be in a small data model, in which case
a normal string copy routine can not be
used since it assumes the pointer size
is near.
*/

FP_SEG(fptr), FP_OFF(fptr),
strlen(str) + 1);
/* display string (note the F modifier) */
printf("Far string is: %Fs\n", fptr);
/* free the memory */
